Definitions
- the present invention relates to a process for obtaining compositions perfumes and perfumed products and products obtained thereby.
- the present invention relates in particular to their use in the field of perfumery.
- Said compounds have interesting olfactory properties and can be used, inter alia, for the preparation of compositions perfumes and scented products.
- esters of hydroxybenzoic acid defined below, presented original olfactory properties.
- the subject of the present invention is a method for obtaining perfume compositions, perfumed substances and products intended for perfumery characterized in that one adds to the constituents usual of these compositions, substances and finished products, an effective amount of a methyl ester of 4-hydroxy-3-methoxybenzoic acid and / or of acid 4-hydroxy-3-ethoxybenzoic acid.
- the present invention also relates to perfume compositions, perfumed substances and products characterized by the fact that they include, title of active ingredient having an influence on the odor, an effective amount of a methyl ester of 4-hydroxy-3-methoxybenzoic acid and / or 4-hydroxy-3-ethoxybenzoic acid.
- the invention therefore lies in a new use of said esters, such as fragrance ingredient.
- the aforementioned compounds have a strong, very spicy, vanilla odor interesting and different from that of vanillin.
- fragment compositions mixtures of various ingredients such as solvents, solid or liquid carriers, fixatives, compounds various odors, etc., in which the methyl esters of the hydroxybenzoic acids, which are used to provide various types of finished products, the desired fragrance.
- Perfume bases are preferred examples of compositions perfumes in which the methyl esters of the acids hydroxybenzoic agents can be advantageously used.
- Toilet waters, aftershave lotions, perfumes, soaps, bath or shower gels or deodorant or antiperspirant products, whether either in the form of sticks or lotions are examples of substances or finished products in which the methyl esters of acids hydroxybenzoic bring their original note.
- perfume talcs or powders of any kind can also perfume talcs or powders of any kind.
- They can also be suitable for room air fresheners or any cleaning product.
- compositions in which said compounds can be introduced advantageously is represented by usual detergent compositions.
- These compositions include usually one or more of the following ingredients: surfactants anionic, cationic or amphoteric, bleaching agents, brighteners optics, various charges, anti-redeposition agents.
- surfactants anionic, cationic or amphoteric bleaching agents, brighteners optics, various charges, anti-redeposition agents.
- the nature of these various components is not critical and the methyl esters of acids hydroxybenzoics can be added to any type of detergent composition. They can be introduced into fabric softeners, in liquid form or in the compositions deposited on a support, most often a nonwoven, intended for use in dryers.
- compositions according to the invention in methyl ester of acids hydroxybenzoic acid expressed as a percentage by weight in the composition considered depends on the nature of said composition (base for perfume or water of toiletries for example) and the power and nature of the effect sought final product level. It goes without saying that in a perfume base the content of hydroxybenzoic acid methyl ester can be very important, for example greater than 50% by weight and can reach 90% by weight while in an aftershave perfume, eau de toilette or lotion, this content may be much less than 50% by weight.
- the methyl ester content of hydroxybenzoic acids can be in detergent compositions, in particular household or in soaps, in the range of 1 to 2%.
- the lower limit of the methyl ester content of acids hydroxybenzoic acid may be the one that causes a noticeable change in the smell of the fragrance or the note of the finished product. In some cases, this minimum content may be of the order of 0.01% by weight. We can obviously use contents not included in the limits of the indicated contents above without departing from the scope of the present invention.
- One of the access routes to the methyl esters of acids hydroxybenzoic acid consists in reacting 4-hydroxy-3-methoxybenzoic acid and / or 4-hydroxy-3-ethoxybenzoic acid and methanol, in the presence of an acid catalyst.
- the various reactions are carried out in the presence of a catalyst classic acid type. Mention may be made in particular of sulfuric acid, p-toluene acid sulfonic, alkyl titanates, preferably isopropyl titanate or n-butyl, antimony oxide.
- the amount of reagents present is determined so that the methanol is generally in excess compared to hydroxybenzoic acid.
- the excess varies widely, preferably from 50 to 500% relative to the amount stoichiometric. It is more preferably chosen between 100 and 200% of the stoichiometric quantity.
- the amount of catalyst used is advantageously chosen between 1 and 5%.
- the reaction temperature is chosen so that it is sufficient to allow the reaction to take place.
- the reaction temperature is preferably chosen between 50 and 150 ° C.
- the reaction is advantageously carried out at atmospheric pressure.
- the reaction is preferably carried out under an atmosphere of an inert gas which can be nitrogen or a rare gas, preferably argon.
- the method according to the invention is simple to implement in action.
- the different reagents can be introduced in any order.
- the order of the following reagents is chosen: hydroxybenzoic acid and methanol, then the acid catalyst.
- the reaction medium is brought to the desired temperature, while maintaining the reaction medium with stirring.
- a preferred variant of the invention consists in eliminating it from the reaction medium, at the as and when they are formed, by any known means, in particular by azeotropic distillation (toluene, cumene or pseudocumene).
- the methyl ester of the hydroxybenzoic acid formed can be recovered. from the reaction medium, by any appropriate means.
- the amount of base, preferably soda, carbonate or bicarbonate sodium is such that the pH is between 6 and 8.
- the organic phase is separated and fractionated by distillation. We most often, collects excess methanol and then the methyl ester of hydroxybenzoic acids.
- the perfume obtained is of the spicy perfume type.
- the methyl ester of 4-hydroxy-3-ethoxybenzoic acid was prepared.
- the olfactory description of the product obtained is eyelet.
